week after the bombing in boston, we have the story of a young woman who refuses to let the loss of her foot keep her from dancing again. Abc's gio benitez now on her hope grounded in science and spirit. Reporter: Today a smiling dancer graces the cover of the "boston herald" -- with her husband, a u.S. Airman, just back from afghanistan. A week ago, adrianne haslet and adam davis were at the boston marathon, watching from the sidelines when the bombs went off. We sat up and I said, wait, my foot hurts, and then he held up my foot and we both just screamed bloody murder. I didn't feel heat from it, i just felt air and then I fell to the ground. Reporter: The blast had torn off adrianne's foot. It's a huge loss for this baltimore dance instructor at arthur murray stewed yods, but she hasn't lost her spirit. It's very sad and i absolutely want to dance again. Reporter: And dr. Linda arslanian says, she will. Reporter: So, doctor, a lot of these victims are telling you, you know what, I will walk again. They can? They can. If they were walking before they had their amputation, we can have them walk again. Much depends on the level of their amputation and all of it depends on what their goals and objectives are. Reporter: And we've seen just how impressive these prosthetics can be. Our own diane sawyer interviewed amy mullins, both her legs amputated as young girl. She later not only competed in the paralympics, but became a model. Whether it's dancing or running, the doctors said modern prosthetic technology is so advanced, adrianne will get back on the dance floor. I just want people to know that you can come out of a situation that might seem like the end of the world and come out stronger. Reporter: This dancer, like the rest of the city, is determined to get back on her feet again.
